Electric housing for an automobile

The housing has control circuit comprising a micro-controller (16) for partially controlling fuses of the housing to assure operation of a comparator (41) and a filter (43). A processing unit (25) determines whether an electric battery is connected to an electric generator of a motor vehicle or disconnected from the electric generator. The control circuit informs a logic controller (29) about a connection state of the battery with the generator or a disconnection state of the battery from the generator, via a multiplexed connector i.e. local interconnect network (LIN)bus.
